What is the responsibility of a servicer if a cancellation of PMI on a borrower that has always paid on time and the cancellation did not happen until borrower called and the loan to value was already down to 62%. Is the servicer force to return the premium paid for the period that borrower was no longer required to carry PMI.

If you failed to properly cancel/terminate the PMI under HOPA then you must refund the unearned premiums. Make sure you review HOPA to understand the difference between the Borrower Cancellation and Automatic Termination timing requirements, especially the 79% and/or 50% automatic termination requirements. If you missed the automatic termination requirements then you will need to refund all the unearned premiums that have been collected.

Thank you so much.
